K7.2 UNLOADER 4.2-6.6 GPM 3500 PSI

The unloader valve diverts water flow into bypass when the trigger gun valve is closed. Flow actuated unloaders divert water to the bypass when there is a sufficient reduction or stoppage of water flow. The flow actuated unloader has an orifice instead of a check valve in pressure actuate unloaders. when the gun valve is closed and water flow stopes, system pressure is increased rapidly al all points past the orifice.A small channel in front of the orifice allows the increased pressure to travel up to the piston assembly, pushing it down. The rest of the water flow is diverted through the bypass and back to the float tank or pump inlet.

Thank you for browsing our selection of pressure washers, steam cleaners and accessories.

We have the tools you need to effectively use and maintain your pressure washer.  Quick connect and rotating turbo nozzles are available in various sizes and configurations.  It's important to use the proper size nozzle for your pressure washer.  Nozzles are sized by looking at the PSI and GPM of your pressure washer.  Quick connect nozzles make it easy to change spray patterns or replace nozzles when they are bad while using the same spray wand.

Pressure washer hoses and hose reels will help you reach your work area, and specialized spray guns with different angles and lengths of wands will make certain jobs easier.

To keep your pressure washer working properly, routine parts and maintenance could be required.  Pressure washer pumps, unloaders, and motors should match the specifications of your particular machine.  Hot pressure washers and steam cleaners require additional components like burners, ignitors, and fuel pumps to allow them to heat the water.

There are a number of different accessories for your hot or cold pressure washer to clean different areas.  Surface cleaners are great for cleaning large areas like parking lots, gas stations, industrial facilities, and school yards.  Duct cleaners are designed to clean trash-chutes, vents, ducts, restaurant hoods, tanks and more. Wet sand blasters can be used on various surfaces to remove most coatings down to white metal, for graffiti cleaning, or paint surface preparation.
